PRODUCTION OF JUSTIFIED LINES O1 SINGLE TYPE.

Application filed May 19,

This invention relates to the casting and composing of justified linesof single type bodies in automatic or record strip controlled typecasting and composing machines.

The invention refers more particularly to casting and composing machineswherein are employed two separate or separately adjustable moulddimensioning devices, one of which determines the extent of opening ofthe mould for normal types and the other determines a variation in theadjustment of the mould for the production of justification types orspaces to produce justified lines of composition.

In these machines, the matrices from which the types are to be cast, areassembled or mounted in a die case in columns or rows according to theirunit value and the normal mould adjusting device for dimensioning themould in accordance with the set dimensions of Width of the variouscharacter types is in the form of a wedge which is positioned for eachtype, generally by the die case positioning mechanism, to bring theproper part of the wedge into position to act as astop for a moulddimensioning blade. The second or justification mould-dimensioningmechanism acts inconjunction with the normal wedge and determines thedimension of the mould for justification types or spaces. This mechanismcomprises two independently adjustable wedges which are positioned,through signals in the record strip, before the casting of a line ofcomposition commences, but are only brought into operation to act inconjunction with the normal wedge on the presentation by the recordstrip of a signal denoting a justification space. Concurrently with thepresentation of such a signal, transfer devices, also in the form ofwedges, are operated to transfer the control of the mould from thenormal wedge to the control of thenormal Wedge, plusthe justificationwedges.

The normal wedge is calculated in frac tions or units ofthe set value ofa particular fount of type, whether the wedge is a straight taper or, asis generally the case, it has a stepped surface in addition to thetaper; therefore, a particular normal wedge 1924. Serial No. 714,351.

is necessary for every different fount or set of type.

Hitherto, the justification Wedges have been calculated so that thedifferent stages of advance have been in fractions of an inch. The twojustification wedges have not the same taper; one of them is a finertaper than the other, so as to provide for minute adjustments.

With these two mould adjusting devices, a record strip composed for onefount of type or type of a particular set width, can only be employed tocontrol the casting machine to produce j ustilied composition of aparticular set and to a particular measure and could not be employed toproduce justified lines of type in any other set or measure, sincealthough the character types would be produced in proper widths, themould being under control of the normal or set wedge, the justificationwould be inaccurate owing to the dimensions determined by thejustification wedges.

It has been proposed, according to United States Letters Patent No.1,449,489, dated March 27, 1923, to equip machines of the kind referredto with a single mould di mensioning mechanism competent to perform thefunctions of dimensioning the mould for both the production of normalbodies and the production of justification bodies with the furtherfunction of distributing or apportioning the line shortage equally amongthe justification bodies to produce exactly justified composition. Thissingle mechanism is competent to produce justified composition ofdifferent set sizes under the controlof the same record strip.

According to the present invention, it is possible to employ one recordstrip to produce justified composition in different sets for whichpurpose this invention proposes to provide justification wedges basedupon units of the type or set, so as to correspond with the normalwedge, so that it is only necessary when composition is required to becast in a difierent set from that in which the record strip has beencomposed, to

change the normal or set wedge as hitherto,

and to employ a different pair of justification wedges, the tapers ofwhich have been especially calculated for the set or fount employed.With such wedges, the composition will come out in a measure or lengthof line, different to, but proportional to the set or measure for whichthe record strip was originally composed.

The justification wedges are set or positioned by a mechanism controlledfrom signals in the record strip. The record strip.

wedges.

For the purpose of the present invention it is no longer necessary toemploy on the record strip composing machine a different justificationdrum or indicator for every set size. A single drum is used for all setsizes. \Vith the present invention a record strip which has beencomposed in a set and measure, suitable say, for a book, can be employedto produce a justified composition suitable for a newspaper.

The invention will be described as embodied in the mould dimensioningsystem of a machine constructed in accordance with United States LettersPatentNo. 625,998, dated May 30, 1899.

Referring to the accompanying draw- 1ngs:

Fig. 1 shows the wedges in position for controlling the mould for normaltype bodies.

Fig. 2 is a cross section through the wedges of Fig. 1 on the line ofthe mold blade.

Fig. 3 is a plan view showing the wedges in position for controlling themould when justification types are being cast and,

Fig. 4 is a cross section through the wedges of Fig. 3 on the line ofthe mold blade. 7

A is the normal wedgeB and G are the justification wedges, and D and Eare the transfer wedges.

As will be seen in Figs. 3 and 4, the normal wedge A and the lowertransfer Wedge E rest and slide upon the base plate F. The uppertransfer wedge D rests upon the lower transfer wedge and the twojustification wedges B and C slide upon a step F on the base plate orblock F. This base plate is provided with two shoulders F and F whichform stationary abutments for the wedges. When normal or character typesare being cast, the wedges are in the position shown in Figs. 1 and 2.The normal wedge A is set to the unit position for the type to be cast,and an abutment H connected with the mould dimensioning blade G bearsagainst the outer edge of the normal wedge, while the lower transferwedge E is interposed between the shoulder F on the stationary abutmentand the inner side of the normal wedge.

In this position the upper transfer D is pushed back or withdrawn asshown in Fig. 1, so that it is inoperative and does not bear againsteither the normal wedge A or the justification wedges B, C.

The normal wedge A, as above stated, is positioned simultaneously withthe die case for each separate type and the die case is controlled by apositioning mechanism through the signals in the record strip, but forall dimensioning purposes, the normal wedge, as it always moves inunison with the die-case, can be recorded as in one with the die case.

When the justification types or spaces are to be cast, the twojustification wedges which have been set or positioned for determiningthe justification fraction to be added to each justification space typebody in the particular line are brought into operation through thetransfer wedges. To accomplish this, mechanism (which need not bedescribed here) is operated to move the lower transfer wedge into anonoperative position as shown in Fig.3, and to advance the uppertransfer wedge so that it forms an abutment between the normal wedge Aand the two justification wedges B and C which in turn, are pressedagainst the upper shoul der F of the stationary plate F. In thisposition, the control of the mould is through the normal wedge A, theupper transfer wedge D and the two justification wedges B and G.

In this latter position, the mould is dimensioned according to the valueof the normal wedge, plus the increment denoted by the two justification wedges.

This arrangement does not differ from that used in the machine hitherto,except, that in accordance with the present invention, when the mould iscontrolled for justification types, it is no longer dimensioned by anormal wedge representing units of set and two justification wedgesrepresenting fractions of an inch, but by a normal wedge representingunits of set and two justification wedges also representing units ofset. By means of this invention, using justification wedges, which havetheir taper based on units of set, justified lines of single types canbe produced, in a different set or measure to that for which the recordstrip has been originally composed; thus, a record strip composed toproduce composition of column width or measure such as is employed innewspapers, can be employed, by simply changing the justificationwedges, to produce justified composition of widths or measures for booksand in various sets.
